Good TD and Toss games on steam?

Prime World: defenders is a decent TD even if it's a bit grindy. And the best of all Defense Grid(with the Containment DLC).

As for toss games, that's a mostly flash genre. Try Snuggle Truck for starters.

TD: Defense Grid and Defender's Quest are my two favorites.
Toss... don't know! :D

iBomber Defense
Pacific

Primeworld td have a lot bugs with achievement, but it's really good (and mostly hard) game

"if you don't know what I'm talking about they are very popular and very awesome games."

Oh OK, now I totally know what you're talking about, great explanation!

Fieldrunners 2 is a bit hardcore even at normal for some people. But it's crazy fun and you can feel a sense of accomplishment on the game.

The game actually made me plan a diagram of turret type positions before implementing it in game lol

age of war : alien hallway
gemcraft : defender's quest, super sanctum td, revenge of the titans

maybe swords and soldiers can become an alternative to age of war (haven't tried it yet).

Kingdom Rush is a must get TD game. It's not like the iOS version or any mobile version.

try anomaly:warzone earth, TD as the attacker. its cool
would angry bird count as a toss?

Gemcraft, Gemcraft 0 and Gemcraft Labyrinth love these games

Played them like 100 hours on kongregate, i wold like to see them on steam

On steam i wold recommend Prime World: Defenders

TD: Plants vs Zombies
Toss: Rock of Ages, if I got that right.
